AH HAH! I knew he was gonn’a do it! Fred is making the classic villain mistake. Leaving at the moment when his victory would have been certain as a means to taunt the heroes. That tactic falls right in with the “bringing-the-hero-on-the-the-verge-of-death-then-spend-fifteen-minutes-explaining-their-diabolical-plot-while-the-hero-plans-a-counterattack” strategy. He’s totally gonn’a regret that.

yeah, you pretty much just never sit there and gloat… never ends well for you. least he didn’t do the “I’ve constructed an elaborate killamajig machine and will now exit the room and close the door so there’s no witnesses… nothing will ever go wrong with that!”
